GOEPORATIGN 3F SPENNSYL- @113 AND GAS SEPARAEOR.

i provide sud improved automatically ole oil and gas separator, partieulerly desi nefl for use in the oil fields in separatthe gas and oil as the fluid comes from o well 'ihe accompanying drawing, which illustrates on application of my invention, igure 1 is e broken secsionel view of a ere-ion oi a tank showing my float actuated very solve mechanism applied. thereto; 2 is a detailecl view partly in plan and in horizontal section, the section been on line ill1 of Fig. 3;YFig. 3

This task is in communication Well by means of a fluid intake having o, connection i estendegl lzhrough she cover 2. In prsciice, she time. 1 is arose-ed hear an oil tank or receptacle 5, mi tshlrs l and 5 being connected roe-ens of joint-ed liquiii discherge pigs i a gushes an overflow ips leacilog rior or the tank to the eXzeror communication-with the oil by means of pipes 8 and 9, and s a fluid or gas discharge pipe 'om the interior of ishe tank/l to nt point. 'istic and important feature of f "31 5 invention is float octueieo ote valve mechanism applied so the lower seal of the tank and desiguecl to automaticellv corfi oi she message of the oil or liquid frorh lbs 1 erior of the look 1 to the tank 5. lllUSiJiabQil and as preferred, she rotary eferriog to the drawing, 1 designates 2.

Serial No H8347.

valve mechanism comprises a casing 11 provided with a flange 12, the latter having a series oi bolt holes 13 adapted to receive a series of bolts 1% passed through said holes 13 and a Wall of the tank 1, well as o reinforcing plate 15 disposed on the interior of the tonic Said valve casing also has formed integral therewith an annular flange 18 by means of which. the discharge pipe 6 is connecteoswiih the valve casing.

The valve, casing is formed with an integral por Bil valve seat 1'? having a series of concentrically arranged ports 18, 19, 20 and 21, the cross sectional area of the ports 18 ami 19 very in size, and said ports are both smaller than the ports'20 and 21.

Located Wihin the valve seat, I provide a, ported valve 22 having ports 23, 2s, 25, and 26 respectively adapted to cooperate with the ports l8, 19, 26 and 2101 the valve seat.

g. 1 shows the rotary valve 22 closed, cutting ofi communicetion with the interior of the tank and the liquid discharge pipe, and Fig. 4 shows the valve open with all hi the ports of the valve 22 registering'with the ports oi the valve seat. The relative position of the ports 23, 24, 25, and 25 of the valve proper with respect to the ports in the valve seat is such that the port 26 as charge of the liquid throughthe discharge pipe, oepending upon the varying height of the liquid Within the tank 1.

@oogoeetecl with the valve 22 by means of arms or levers 27, is a, ball float 28. Float 28 is attached to the outer ends of levers'27 by means of a cross-rod 29, passing through the center of iioot 28, and nuis 30. Located between the float 28 and the valve 22,- 1 provide across-rod and a sleeve 32 designed to connect the rods 2'? at point intermediate their ends, thereby providing a "rigid frame. The opposite ends of the levers or 22 by means of a rod 33, which latter is passed through the center or valve 22 and has its ends projected. through holes in the rods 27 These parts are then tied together hy nuts 3%.

2o in the valve and seat.

What 1 claim is z"- 1. A valve casing, a cylindrical valve seat in said casing provided with a plurality'of difi'erently sized ports, and a rotary valve in the seat provided with ports'iof e ual areas, the ports in the valve being 0 set with respect to those in the seat so that a relative movement between the valve and casing in one direction will gradually increase the communicating port areas in the valve and seat,

' 2. A valve casing, a cylindrical valve seat in said casing provided with a row oi ports' of gradually increasing size, and a rotary valve in the seat provided with a row of ports of equal areas, the ports in the valve being oilset with respect .to those in the seat so that a relative movement between the valve and casing in one direction will gradually increase the communicating port areas 3. A valve casing, a cylindrical valve seat in said casing provided with a row of differen'tly sized ports, and a, rotary valve in the seat provided avith a row of ports all of which are substantially the same size as that of the smallest port in the valve seat,

a the portsin the rotary valve being ofiset with respect to those in the seat so thata relative movement between the valve and casingin one direction will gradually increase the communicating port areas in the valve and seat;

4:. Valve mechanism for separators comprising a casing, a cylindrical valve seat in iioatinechanigi within the supply to than intake for automatically operating the valve mechanism, said seatvhavmglparallel differing in'port area. L

5. Valve mechanism for separators cflim prising a casing, a cylindrical valve in 1 5' said casing. permanently open'toithe" outlet, said seat havin its axis extendin horizotr. tally, and a cy indrical rotary/v ve in the seat and permanently open at its end to the intake, said valve and seat havin' 6 relatively arranged 'to permit gracfuariw crease of communicating'port area between the intake and ofi take by movements of the valve in one direction, incombination-with float mechanism within the supplyto the inl take for automatically operating the valve meohanism, said seat having parallel ports differing in port area," said valve having 7. parallel ports of substantially similar aregjf 6. Valve mechanism for se arators com-i5 prising a casing, a-Jzylindria valve seafliixj said casing permanently open to the outlet,

said seat having its axis extending. horizon-- tally, and a cylindrical rotaryvalve in the seat and permanently open at its end to the If. intake, said valve and seat having orts relatively arranged to permit 'gradua in, crease of communicating port area between the intake and oil-take by movementsot thel valve in one direction, in combination with 7 float mechanism within the supply to the intake'for automatically operating the valve mechanism, said seat having parallel ports differing in port area, said valye having parallel ports 0 substantially-similar area, said 3" valve ports being ofii'set with respectto the seat ports,

In testimony whereof I affix my signature in presence of two witnesses.
